The passage from the first of these two positions to the second necessitated rstly a pivoting movement (Figs. 3, 4) and. secondly a sliding movement (Figs. 4, 5).

If, on the contrary, the case being in position of Fig. 5, it is desired to protect the glass and the dial, the above mentioned movements are irrversely effected, that is to sayprstlyra stiding movement in the direction of the arrow l (Figs.

5, 4) and secondly a pivoting movement in thedi-4 Y rection of the arrow 9 (Figs. 4,3).

. The invention further provides means for preventing the pivoting movement when the pivots.

are in a position other than of Figs. 3 and 4; These means consist in the' bottom of the watch case being provided with a narrow rim oneach ofthe sidesv coming into Contact with thefguides and a supplementary gl'ide4 I2'. parallel t0 each 0fy the'v guides 4 of me' support 2. ,The width 'between the guide 4. andthe. guide I2 is .the same as the Width between the guide 4' and the upper part 13 (Fig. 6v) of' the support 2 andthe guide 1,2 1 and 351 fitting together the` twoparts' of the watch'` this' part 13 are joined together by a semi-circular` part y14- haafing as centre thecorresponding ex.- trei'nity` of the guideor groove'4.

" as represented in Figs. 621, 6'5',it is seen that the rm 11 of thecase 1 will come to bear on the upper partfIS o1A the Support 2. O'n the contrary, Figs.` 3 andi 4. show qclearly how this rim 11 can :slidetangentially on the semi-circular surface 14 when the case pivots. Fig. 5 further shows clear- 1y how the rimll penetrates into the rsupplementary guide' or groove 14 when the case slides rorngthepositon of the Fig. 4 intovthe positionl o1 the 5. It is also clearly seen that this arrangement prevents the watchy from pivoting when the pivot 5 is not in the centre of the semicircle' formed by the. surface ofv part I4. y

The invention also provides a device-intended 593 to` maintainthe watch case inV `each of its two 5.5; in` detail ow these smallv balls 15 areV retained by'` a face such as 16Y of the watch ease in a lodg-r 69# sitions as shown. in Pig. 3 or Fig. -5, the bans 15 lightly penetrate into the guides or grooves 4 thus 7:1 construction as regards theV meansyintended to final positions. This deviceconsists in two smal-l balls 15`s`ituated inthe watch case 1, fromwhich they emerge slightly dueV to .the action of a spring,

as in Figs. 6 and 6c.` The Fig.V 6c shows ment V1'1 ofthis case and how the spring 18 tends to push them towards the outside.

. When the watch ease vis in one of the nal po preventingA the case fromvsliding or pivoting without boing touched. The balls hold it in placev iny the manner of a press-stud.

Given thsslight` resistance` offered by this fixation to thepivoting of the watch case from Vthe position ofFig. 3 to that of'Fig. 4 andin order to facilitate the. necessary raisingv of 'this casein fthe direction of the arrow 19, the case is fur- Aribbed withaprojction 20.4

Thewatch represented in Figs.' 7,18, 8a 'and `8b ofthehdrawlngs, functions in exactly the same we? as the watchjust described, but differs in its l position of Fig. 11.

assure the immobility of the pivots at the moment of pivoting.

This watch, therefore, also consists of the case 1 and its support 2, a part of which has been represented in perspective on Figs. 8a and 8b. The support 2 also comprises two grooves or Vguides 21 different from the grooves 4 in that their width is smaller than the diameter of the correspondingy pivot, this pivot 22 possesses, as seen in Fig. 8a, a flat cut part 23 so as to be ableto penetrate into the groove 21, without however being able to turn therein as the width oi'this groove does not correspond to the diameter :of the pivot 22.

At one of its extremities, the groove 21 has a larger circular part 24 corresponding to the diameter ofl the pivot 22, and in which this pivot can then turn.

Fig. 7 shows the watch case 1 in the position where its pivot can turn, that is to say, in the .pivoting position. Flg. 8, onthe contrary, represents the watch case during the sliding movement and in a position where the pivot 22 cannot turn' in the guide or groove` 21.`

This watch is alsomaintained in itssupport by balls 15 similar to those represented in Fig; 6c. lThe' watchv according to Figs. 9 to 15 and'. 15a' to" 15o differs from the preceding ones in that it can pivot at both ends ofthe guidesY of its support and by various other details which will appear from the following.

The watch also consists of the case 1 and a support 2, the case 1 being able to be placed inj the support, `either in the non-protected posi# tion` of Fig. 9, or in the protected position of Fig. 13, the other figures showing intermediate positionsbetween these two extreme or final positions. The watch'V strapl is fixed -to the small bars 25. v

` The case 1 'of the watch also possessespivots 26 intended topenetrate intothe guides or grooves 27 of the support 2 in order to allow the sliding and pivoting movement of said watch case.

As will be seen'from the drawings, the' guides or grooves 27 are not rectilinear as in the preced-` ing examples, -but slightly curved. The same ap plies tothe bottom 28 of the support and the faces 29 and 30 (Fig. 14) forming the bottom and the top of the Watch case 1. 'This curved form of these various parts results in the watch sliding, not in one plane, but in a portion of a cylindrical surface of very large radius. Thus insliding, the Watch case is :raised slightly as 'it leaves its support, a movement which is particu-` larly visible on Figs. 10 and 11, the rst show.

an intermediary position and the second the final position occupied bythe case 1 when it is caused to slide in the direction of the arrow 31 on Fig.,9.

The turning over of the case from the-position of Fig. 9 into the position of Fig. 13 is therefore effected. by pushing thecase in thc direction of the arrow 21 through the inter` mediary position of Fig, 10 in theextreme sliding the direction of the arrow 32, through the intermediary position yof Fig. l2, thewatch is pivoted until it reachesthe position as represented in Fig. 1,3. .This lattermovement is eiected on the pivots 26 situated at this moment at the left extremityof the guides or grooves 27 as shown in the drawings.

Inversely, in order to bringthe case back into its original position, it is-pushed inv the rdirection of the arrow 33 on Fig. 13 so that it slides 7 From this position and in` Y the iin'al Iposition of Fig. 9.7.1 In 4 effecting;v this latter movement, the case turns on the pivots now Vbeing situated in r the rguides or g grooves 27, on, f

In order to assurethe position of' the4` pivots 26 during the-pivoting movement 'which cannow be, effected at both'extremities of the'guides 27,

these guides.A posses aconical cut outpartij34-in Whichpenetrates a corresponding conicalpart of;

The Figs. laandlbshow thejdetails` of this construction, thepivot 26-having a conical part 35 able to penetrate into thecorresponding conical cutout part 34 ofthe guide 427. Forthistpur pose, the pivot 26 is mounted in a similari man-l Y ner to the ballA 15 representedgin'Fig.-j6c, asmay spring 36h.

be seen` from Fig. 15o, where the ,pivot-- 26 withl its conical part 35is subjectedgtothe action o f a same way as in the -preceding cases,-- with thisr difference that each ball enters into ,the lnal posi-` tions in the corresponding conicaL cut out ,parts 34 of the grooves 27.1

' In order to avoidthe Vwatch` case pivoting in another position than that where the pivot is housed in the corresponding conical cutout'parts 34 of theguides 27, the support 2Vof the case 1v possesses two cylindrical grooves 37 ,having as their geometrical axis, the pivoting axis of the case in each of `its two'extreme sliding positions. The corresponding front side 38 of the watch case l, is also in theA formof aportion of a cylinder whose axis would p be the of the case, thisfront side being intended to 'penetrate intothe' corresponding cylindrical groove 37 during the pivoting movement.

n This groove being deeper, that is to say, its bottom being further away fromV the guide'27 than the curved bottom 28 of thesupport 2, the pivoting of the case can only takeplacewhen its front side 38 is above one of the grooves 37 andthe pivots'l 26 in v the corresponding conical cut out parts 34.

The fact that (during the sliding movement the watch case is slightly raised in relation to its support, is very importantinv that it facilitatesv the pivoting. It is easier `to pass rWiththe finger under the case in. order to turn it, if this case is raised instead remaining pressed against the arm.
